INDEMNIFICATION

8.01 Seller Indemnity. Seller shall indemnify and hold Purchaser and its affiliates harmless at all times from and after the Closing Date from and against any and all claims, liabilities, losses, damages, costs and expenses (including reasonable legal fees, costs and expenses arising from or in connection with any action, suit, proceeding or claim incident to any of the foregoing) (collectively, “Purchaser Losses”), suffered or incurred by Purchaser or its affiliates resulting from:

(a) subject to Section 8.06 below, any breach or inaccuracy of any representation or warranty made by Seller in this Agreement or in any Transaction Document (for purposes of this Section 8.01(a), the representations and warranties set forth in Sections 3.07, 3.08 and 3.09 shall be read without reference to materiality or knowledge qualifiers);

(b) any breach of any covenant, agreement or undertaking made in this Agreement or in any Transaction Document by Seller; or

(c) any fraud, willful misconduct or bad faith of Seller in connection with this Agreement, the Transaction Documents or the transactions contemplated hereby or thereby.

8.02 Purchaser Indemnity. Purchaser shall indemnify and hold Seller and its affiliates harmless at all times from and after the Closing Date from and against any and all claims, liabilities, losses, damages, costs and expenses (including reasonable legal fees, costs and expenses arising from or in connection with any action, suit, proceeding or claim incident to any of the foregoing) (collectively, “Seller Losses”), suffered or incurred by Seller or its affiliates resulting from:

(c) the Guarantees, the Bond Documents or the Letter of Credit Agreement; or

(d) any fraud, willful misconduct or bad faith of Purchaser in connection with this Agreement, the Transaction Documents or the transactions contemplated hereby or thereby.

8.03 Survival. The representations and warranties of each Party hereto contained herein or in any certificates or other documents delivered pursuant to this Agreement and any indemnification obligations related thereto shall survive the Closing

-17-

until the first anniversary of the Closing; provided that the Seller Fundamental Representations and the Purchaser Fundamental Representations and the indemnification obligations related thereto shall survive indefinitely; and provided, further, that any representation or warranty will continue to survive if a written notice of a breach thereof shall have been timely given to the breaching Party by the other Party on or prior to such termination date, until the related claim for indemnification has been satisfied or otherwise resolved as provided in this Article VIII. Seller’s indemnification obligations under Sections 8.01(b) and 8.01(c) and Purchaser’s indemnification obligations under Sections 8.02(b), 8.02(c) and 8.02(d) shall survive indefinitely.

8.04 Indemnification Procedures. Any Party seeking indemnification hereunder (the “Indemnified Party”) shall notify the other Party (the “Indemnifying Party”) promptly after it becomes aware of facts supporting a claim or action for indemnification (whether as a result of or claim by a third party or as a result of a direct claim) under this Article VIII, and shall provide to the Indemnifying Party as soon as practicable thereafter all information and documentation reasonably necessary to support and verify any Losses associated with such claim, or action. The failure to so notify or provide information to the Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to any Indemnified Party, except where and to the extent actual prejudice has been suffered. The Indemnifying Party shall defend, contest or otherwise protect the Indemnified Party against any such claim or action at its sole cost and expense; provided, however, that the Indemnifying Party shall not make any settlement or compromise without the prior written consent of the Indemnified Party. The Indemnified Party shall have the right, but not the obligation, to participate in the defense thereof by counsel of the Indemnified Party’s choice. If Indemnifying Party fails timely to defend, contest or otherwise protect against such suit, action, investigation, claim or proceeding, the Indemnified Party shall have the right to do so, including the right to make any compromise or settlement thereof, and the Indemnified Party shall be entitled to recover the entire cost thereof from Indemnifying Party, including attorneys’ fees, disbursements and amounts paid as the result of such suit, action, investigation, claim or proceeding. Payments of all amounts owing by Indemnifying Party under this Article VIII shall be made within 30 days after notice thereof.

8.05 Certain Limitations. Notwithstanding anything to the contrary set forth in this Agreement, no Indemnified Party shall make a claim against an Indemnifying Party or its representatives for indemnification under Section 8.01(a) (except with respect to breaches of Seller Fundamental Representations) or 8.02(a) (except with respect to breaches of Purchaser Fundamental Representations) unless and until the aggregate amount of such Losses suffered by the Indemnified Parties exceeds $300,000 (the “Basket”), in which event the Indemnified Parties may claim indemnification for only those Losses in excess of the Basket. Further, neither Party’s indemnification obligations under Section 8.01(a) (except with respect to breaches of Seller Fundamental Representations) or 8.02(a) (except with respect to breaches of Purchaser Fundamental Representations) shall exceed in the aggregate $4,000,000. For the avoidance of doubt, the limitations set forth in this Section 8.05 shall not apply to indemnification obligations under Section 8.01(a) (with respect to breaches of Seller Fundamental Representations), 8.01(b), 8.01(c), 8.02(a) (with respect to breaches of Purchaser Fundamental Representations), 8.02(b), 8.02(c) or 8.02(d).

-18-

8.06 Breach of Certain Representations. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, and notwithstanding the limitations set forth in Section 8.05, the Parties acknowledge and agree that Seller and Purchaser shall each be responsible for 50% (and Seller’s indemnification obligations under Section 8.01(a) shall be limited to 50%) of any and all Purchaser Losses resulting from any breach or inaccuracy of any representation or warranty made by Seller in Section 3.07, 3.08 or 3.09.

8.07 Exclusive Remedy. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, the Parties acknowledge and agree that, should the Closing occur, each Party’s sole and exclusive remedy with respect to any and all claims for Losses arising from or relating to this Agreement or the Transaction Documents or any representation, warranty or covenant of the other Party contained in this Agreement or the Transaction Documents shall be pursuant to the indemnification provisions set forth in this Article VIII or otherwise expressly set forth in this Agreement; provided that nothing herein shall limit in any way either Party’s remedies in respect of fraud by the other Party in connection with the Transactions.

ARTICLE IX

MISCELLANEOUS

9.02 Specific Performance; Limitation of Liability. Each Party hereby acknowledges that the rights of each Party to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that, in the event that any Party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching Party may be without an adequate remedy at law. In the event that any Party violates or fails or refuses to perform any covenant or agreement made by such Party herein, the non-breaching Party may, subject to the terms hereof, institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief.

UNDER NO CIRCUMSTANCES SHALL ANY PARTY BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, ARISING OUT OF A BREACH OF THIS AGREEMENT WHETHER A CLAIM FOR ANY SUCH DAMAGES IS PREMISED UPON A BREACH OF CONTRACT, TORT, STRICT LIABILITY OR OTHER THEORY; PROVIDED, HOWEVER, THAT DAMAGES FOR ANY THIRD PARTY CLAIM INDEMNIFIED HEREUNDER ARE DIRECT DAMAGES AND SHALL NOT BE CONSIDERED DAMAGES SUBJECT TO THE FOREGOING LIMITATIONS.

No waiver of any of the provisions of this Agreement shall be deemed to be, nor shall it constitute, a waiver of any other provision whether similar or not. No single waiver shall constitute a continuing waiver. No waiver shall be binding unless executed in writing by the Party making the waiver.
